Chik-blockchain

Added

- We have released version 1.0.0 of [chikpos](https://github.com/Chik-Network/chikpos). This includes a 20% speed increase for bitfield plotting compared to the previous version on the same machine. In many cases this will mean that bitfield plotting is as fast or faster than non bitfield plotting.
- xorinox improved our support for RedHat related distributions in `install.sh`.
- ayaseen improved our support for RedHat related distributions in `install-timelord.sh`.
- We have added Dutch and Polish to supported translations. Thanks psydafke, WesleyVH, pieterhauwaerts, bartlomiej.tokarzewski, abstruso, feel.the.code, and Axadiw for contributions to [translations on Crowdin](https://crowdin.com/project/chik-blockchain).
- The GUI now supports "Exclude final directory" when plotting. This is found in the Advanced Options for step 2 on the plot creation page.

Changed

- Wallet now uses a trusted node and, when syncing from that node, Wallet does not do as many validations.
- jespino changed `chik keys show` to require the `--show-mnemonic-seed` before it displays your 24 work private key mnemonic.
- We decreased the size of the block cache in node to perform better with longer chains.
- You can now add a private key mnemonic from a file with `chik keys show`.
- Flofie caught an error in CONTRIBUTING.md.
- We no longer rely on aiter so it has been removed.
- Keyring deprecated the use of OS_X in favor of MacOS.
- "Broken pipe" error was decreased to a warning.
- Many non critical log messages were decreased from warning to info log level.
- Harvester should now log the plot file name if it finds a bad plot at error log level.

Fixed

- Peer ips were being written to the database on a per ip basis. This caused a lot of wasted disk activity and was costing full node performance.
- We fixed an issue where the last block wasn't fetched by the GUI.
- There was an edge case with full node store that can stall syncing.
- There was a potential node locking issue that could have prevented a Timelord from getting a new peak and cause a chain stall.
- We did not correctly support some Crowdin locales. Pirate English was starting to overwrite US English for example.

Added

- There is now a simple progress bar on the GUI Plot page and when you view the log from the three dots on the right.
- Users must now explicitly set the `--show-mnemonic-seed` flag to see their private keys when running `chik keys show`.
- We are now building Linux GUI installers. These should be considered beta quality for now.
- Translations now available for German, Traditional Chinese, and Danish. Thanks to Dravenex, MaestroOnICe, loudsyncro, loppefaaret, thirteenthd, wong8888, N418, and swjz for all the translation help. You to can translate at our [Crowdin project](https://crowdin.com/project/chik-blockchain/).

Changed

- The mainnet genesis is now in the initial config.yaml and the green flag components have been removed.
- Our release process and branching strategy has changed. CONTRIBUTING.md will be updated in the main branch soon with details.
- This mainnet release does not migrate previous testnet configuration files.

Fixed

- Weight proofs, especially wallet weight proofs were failing when some Blueboxed proofs of time were encountered.
- Users can now pip install e.g. chik-blockchain==1.0.1 on most platforms.
- Sometimes the GUI had an error regarding MainWindow.

Added

- This is the first production release of the Chik Blockchain. This can be installed and will wait for the green flag that will be dropped at approximately 7AM PDST (14:00 UTC) on Friday March 19, 2021. All farming rewards from that point forward will be considered valid and valuable XCK. There is a six week lock on all transactions. During those six weeks farmers will be earning their farming rewards but those rewards can not be spent.
- Initial difficulty will be set for 100PB. This may mean the initial epoch may be slow. Mainnet difficulty resets are targeted for 24 hours so this difficulty will adjust to the actual space brought online in 24 to 48 hours after launch.
- Transactions are not enabled in the 1.0.0 version and will be soft forked in during the six week period via a 1.1.0 release.
- There will also be a 1.0.1 release after the green flag process is complete to simplify install for new users by removing the green flag alert. In the interim there will be new testnet releases using the 1.1bx version scheme.
- Starting with release 1.0.0 you usually no longer need to upgrade and 1.0.1 will be fully optional. However you will have to upgrade to 1.1 after it is out and before the six week period ends. We plan to give plenty of time between those two events up to and including pushing back the transaction start date by a short period of time.
- Thank you to L3Sota for adding a Japanese translation via our [Crowdin project](https://crowdin.com/project/chik-blockchain).
- The generation of CoinIDs is now unique on mainnet to avoid testnet transaction replays.
- Validation of transactions will now fail after the expiration of the six week period.

Changed

- Weight proof request timeout was increased to 180 seconds.
- Mainnet uses port 9678 and other constants and service names were changed for mainnet.
- GUI locales are now extracted and compiled in `npm run build`.
- Daemon now logs to STDERR also.

Fixed

- GUI plotting on some Macs was not working due to locale issues with Click.
- Thank you L3Sota for bringing this log back into 2021.
- The errant warning on Electron startup has been removed. Thanks dkackman.

Changed

- This is a hard fork/breaking change from RC6/7/8. The current plan is to drop the flag at noon pacific time, today 3/16.
- Using the real prefarm keys for this test

Fixed

- Found and fixed another green flag related issue
- Fixed an issue with weight proofs where all sub-epochs were sampled, and the size of the weight proof kept growing
- Fixed an issue with install-gui.sh, where npm audit fix was failing. (Thanks Depado!)
- Migration with CHIK_ROOT set does not crash chik init

Added

- This is a hard fork/breaking change from RC6/7. TXCK Coins will **not** be moved forward but your plots and keys and parts of your configuration do. When you install this version before 10AM PDST on 3/16/2021 it will load up, start finding peers, and otherwise wait for the flag drop at that time to start farming. This is likely to be the last dress rehearsal for mainnet launch. Our [3/15/2021 blog post](https://www.chiknetwork.com/2021/03/15/mainnet-update.html) has more details on the current mainnet launch plan.
- The GUI now has a tooltip that directs users to the explanation of the plot filter.
- The GUI now has a tooltip to explain the "Disable bitfield plotting" option. Thanks shaneo257 for the idea.
- The GUI now has a tooltip to explain Hierarchical Deterministic keys next to Receive Address on the Wallet page.

Changed

- We now use Python 3.9 to build MacOS installers.
- Harvester now catches another error class and continues to harvest. Thanks to xorinox for this PR.
- We now use a smaller weight proof sample size to ease the load on smaller machines when syncing.
- Starting the GUI from Linux will now also error out if `npm run build` is run outside the venv. Huge thanks to dkackman for that PR.
- `chik farm summary` will now display TXCK or XCK as appropriate.
- We added more time to our API timeouts and improved logging around times outs.

Fixed

- We no longer use the transaction cache to look up transactions for new transactions as that was causing a wallet sync bug.
- Sometimes the GUI would not pick up the fingerprint for the plotting key.
- `chik farm summary` displayed some incorrect amounts.
- Weight proofs were timing out.
- Changes to farming rewards target addresses from the GUI were not being saved for restart correctly.
- Signage points, recent deficit blocks, and slots for overflow challenge blocks had minor issues.

Changed

- Our green flag test blockchain launch worked but it uncovered a flaw in our installer versions. This release is a bug fix release to address that flaw. You should read the RC6 changes below if this is your first time installing since RC5.
- Thanks to dkackman for implementing an early exit of the GUI if you run `npm run build` without being in the `venv`.
- `chik netspace` now defaults to 1000 blocks to mirror the GUI.
- The installer build process was spruced up some.

Fixed

- Setting difficulty way too low on the testnet_6 launch revealed a Timelord edge case. The full node was hardcoding the default difficulty if block height is < EPOCH_BLOCKS. However there were many overlapping blocks, so none of the blocks reached the height, and therefore the timelord infused the wrong difficulty.
- Fixed a race condition in the Timelord, where it took time to update the state, so it ignored the new_peak_timelord form the full_node, which should have reset the timelord to a good state.
- Wallet notoriously showed "not synced" when it was in sync.
- Installers were not correctly placing root TLS certificates into the bundle.
- Weight proofs had a logic typo.
- There was a typo in `chik netspace`. Thanks altendky.
- There was a typo in `chik plots`. Thanks adamfiddler.

Known Issues

- Some users can't plot in the GUI in MacOS Big Sur - especially on M1. See issue [1189](https://github.com/Chik-Network/chik-blockchain/issues/1189)
